摘要： A method is provided for determining presence of a user's hand tremor or intentional motion during recognition of an image through photographing. Image sample blocks of a previous frame are detected by using an edge detecting method. A block distance between the detected image sample block of the previous frame and an estimated image sample block of a current frame is calculated. The calculated block distance is compared with a first threshold. The calculated block distance is compared with a second threshold when the calculated block distance is less than the first threshold.

摘要： Provided is an apparatus and method for generating an image for character region extraction. Upon input of an original image, a candidate character image is generated from the original image and a plurality of binarization maps for similar colors are generated from the generated candidate character image. A binarization map including a background region is selected from among the plurality of generated binarization maps, and the background region of the selected binarization map is expanded. The expanded background region is inverted to generate an image including a character region, thereby generating an image for accurately extracting the character region without missing a boundary portion of a character.
